Answer 1

Volume balok = p x l x t

= 14 m x 30 m x 12 m

= 5.040 m

volume 1/2 tabung = 1/2 × phi x r^2 × t

d = 14 m

r = 14 m ÷2

r = 7 m


1/2 × 22/7 × 7 m x 7 m x 30 m

1/2 × 22/1 × 1 m x 7 m x 30 m

1/2 × 154 m x 30 cm

1/2 × 4.620 m

2.310 m

gabungan

= 5.040 m + 2.310 m

= 7.350 m






volume kubus = s x s x s

= 30 cm x 30 cm x 30 cm

= 27.000 cm


volume limas = 1/3 x luas alas x tinggi

1/3 × ( 30 cm x 30 cm ) × 17 cm

1/3 × 900 cm x 17 cm

300 cm x 17 cm

5.100 cm


27.000 cm + 5.100 cm

= 32.100 cm
